Papua New Guinea Fault and Fold Systems from Geological Surveys

Wellman (1971) presented erroneous data on lineaments in Papua New Guinea. The dataset describes major faults and folds determined by ground and remote sensing surveys conducted by the Bureau of Mineral Resources and the Geological Survey of Papua New Guinea over the last 25 years. It is presented in a discussion paper available in PDF and HTML formats.

Use Cases

• Correcting historical geological maps based on modern survey data mentioned in the description.
• Analyzing fault and fold systems in Papua New Guinea based on ground and remote sensing surveys.
• Comparing suspected strike-slip movements with proven vertical movements for regional tectonic studies.

Strengths

• Based on surveys conducted over a 25-year period by government and oil exploration geologists.
• Incorporates data from airphotos at scales from 1:20,000 to 1:80,000 and side-looking airborne radar imagery.
• Specifically identifies and corrects omissions and inaccuracies in a prior published work.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific surveys conducted.
